Abu al-Ahwas quoted his father saying:

I came to the Prophet ﷺ wearing a poor garment and he said (to me): Have you any property? He replied: Yes. He asked: What kind is it? He said: Allah has given me camels. Sheep, horses and slaves. He then said: When Allah gives you property, let the mark of Allah's favour and honour to you be seen.

حَدَّثَنَا النُّفَيْلِيُّ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا أَبُو إِسْحَاقَ، عَنْ أَبِي الأَحْوَصِ، عَنْ أَبِيهِ، قَالَ أَتَيْتُ النَّبِيَّ ﷺ فِي ثَوْبٍ دُونٍ فَقَالَ " أَلَكَ مَالٌ " . قَالَ نَعَمْ . قَالَ " مِنْ أَىِّ الْمَالِ " . قَالَ قَدْ أَتَانِيَ اللَّهُ مِنَ الإِبِلِ وَالْغَنَمِ وَالْخَيْلِ وَالرَّقِيقِ . قَالَ " فَإِذَا أَتَاكَ اللَّهُ مَالاً فَلْيُرَ أَثَرُ نِعْمَةِ اللَّهِ عَلَيْكَ وَكَرَامَتِهِ " .
